I only have a few pages of Theo’s logbook and a few documents to work with.
This one is most interesting.
At first we would think Theo flew a Mosquito on his first operation.
Theo was with RCAF 418 Squadron at Ford from March 23rd to July 31, 1943. This is a page from his logbook showing what Theo did on March 26.
March 26 Boston III No. S SELF SOLO ON TYPE
Theo soloed on a Douglas Boston III (American A-20 Havoc)
This is the next page of the logbook with his first mission.
